Answer:
For diatomic oxygen:V=539.06 m/s
For carbon dia oxide:V=459.71 m/s
For dia atomic hydrogen:V=2156.25 m/s
Explanation:
As we know that
Root mean square velocity V
Where
R is the gas constant
T is the temperature (K).
M is the molecular weight.
For diatomic oxygen:
M=32 g/mol
T=273+100 = 373 K
V=539.06 m/s
For carbon dia oxide
M=44 g/mol
T=273+100 = 373 K
V=459.71 m/s
For dia atomic hydrogen:
M= 2 g/mol
T=273+100 = 373 K
V=2156.25 m/s
Answer:
Total Energy consumed = 146.94 kwh
Total cost = rs 587.76
Explanation:
Given:
3 bulbs each 60 watt [for 3 hours daily]
4 fans each 100 watt [for 8 hours daily
1 electric heater of 2 kWh (2,000 watt) [for half hour daily
]
Rate = rs 4/Kwh
Find:
Total Energy consumed
Total cost
Computation:
Energy used = Power × time
3 bulbs each 60 watt [for 3 hours daily] = 3 x 60 x 3 x 31 = 16,740 watt = 16.74 kw
4 fans each 100 watt [for 8 hours daily = 4 x 100 x 8 x 31 = 99,200 watt = 99.2 kw
1 electric heater of 2 kWh [for half hour daily
] = 1 x 2000 x (1/2) x 31 = 31,000 watt = 31 kw
Total Energy consumed = 16.74 + 99.2 + 31
Total Energy consumed = 146.94 kwh
Total cost = 146.94 x 4
Total cost = rs 587.76
Answer:
The answer is below
Explanation:
Plants that grow among many tall trees in a dense forest could adapt so that they could get enough air and water through the following means:
1. By becoming climbers. Here they climb up the nearby trees to get more air and sunlight.
2. Plants grow leaves that have pointed tips. This allows the passage of water in the plant's leaves without causing damage.
3. Some plants grow as epiphytes, where they grow on big trees' canopy
Solar eclipse: when the sun, moon, and earth align
Lunar eclipse: when the moon blocks the sun's light
1, there is no water there, so plants cant grow
2, there are no plants, hence, there would be no oxygen.
3, (not sure) the temperature is different from earth and could possible not sustain life
